Description

Technical Field

[0001] This utility model relates to the field of paper tube manufacturing and processing technology, and in particular to a paper tube cutting mechanism. Background Technology

[0002] The paper tube is formed by winding multiple layers of glued paper tape onto a mandrel using a spiral or flat winding process. After the paper is evenly coated with adhesive by an automatic gluing device, it rotates continuously on the mandrel in a spiral or parallel manner, while pressure is applied to ensure that each layer is tightly bonded, increasing the tube wall density and compressive strength. After the paper tube is wound to a certain length, it needs to be cut to separate the paper tube from the raw paper. Because the paper tube is spirally wound, it will rotate and move. Cutting requires stopping the winding of the paper. After cutting, the paper tube is removed from the mandrel. Because the winding needs to be stopped, the efficiency is reduced. Utility Model Content

[0003] The purpose of this invention is to provide a paper tube cutting mechanism to solve the above-mentioned problems.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A paper tube cutting mechanism and a packaging workbench are disclosed. A support base is fixedly connected to the workbench. A horizontal mandrel is rotatably connected to the support base. A horizontal connecting rod is slidably connected to the support base, and a horizontal support rod passes through the mandrel along its axial direction. The support rod and the mandrel are slidably connected. A connecting column connects the support rod and the connecting rod. A moving mechanism is connected to the workbench. A moving plate is mounted on the moving mechanism. An adjusting mechanism is provided between the moving plate and the moving mechanism. A support column is fixedly connected to the moving plate. A cutting machine is hinged to the support column. A rotating mechanism is provided between the moving plate and the cutting machine. The connecting rod is fixedly connected to the moving plate. An mounting plate is connected to the moving plate. The mounting plate is located below the cutting machine. Two horizontal rollers are rotatably connected to the mounting plate. The cutting blade of the cutting machine is located near the end of the rollers, and the mandrel is located above the rollers.

[0005] Using the above technical solution, the paper strip is spirally wound onto the mandrel to form a paper tube. The paper strip continues to wind, and the wound paper tube moves spirally forward on the mandrel. The paper tube moves to the space between the two rollers of the mounting plate, where the rollers support the paper strip. The paper strip continues to wind into a paper tube. After the wound paper tube moves a certain distance outward from one end of the rollers, the moving mechanism drives the moving plate to move. The moving plate drives the cutting machine and connecting rod to move, and the connecting rod drives the support rod to move. The cutting machine and support rod move at the same speed as the paper tube. At the same time, the rotating mechanism drives the cutting machine to rotate relative to the support column, so that the cutting machine contacts the paper tube. The cutting machine cuts the rotating paper tube. During the cutting, the support rod supports the inside of the paper tube to prevent the gas cutting machine from cutting. The force applied to the hollow paper tube causes it to deform, and a section of the paper tube that has moved to the outer end of the roller is cut off. The rotating mechanism drives the cutter to separate from the paper tube, and the moving mechanism then drives the cutter, roller, and support rod to move back. The support rod leaves the cut-off paper tube, and the cut-off paper tube falls off the roller. As the cutter returns, the paper strip continues to wind into a spiral and move forward. The cutter returns to its original position. When the paper tube moves a distance beyond the end of the support roller again, the moving mechanism drives the cutter to move along with the paper tube and cut it. This allows the cutter and paper tube to move synchronously, eliminating the need to stop winding the paper tube. Cutting can be done while winding the paper tube, improving work efficiency.

[0006] Preferably, the rotating mechanism is a cylinder, which is hinged to the moving plate, and the cylinder output shaft is hinged to the cutting machine.

[0007] Using the above technical solution, the cylinder output shaft extends to drive the cutting machine to rotate relative to the support column.

[0008] Preferably, the moving mechanism includes a lead screw, which is horizontally rotatably connected to the upper part of the worktable. The moving plate is slidably connected to the lead screw slider, and the adjusting mechanism is disposed on the lead screw slider and connected to the moving plate.

[0009] Using the above technical solution, the lead screw rotates its slider, which in turn moves the moving plate.

[0010] Preferably, the cutting machine includes a connecting seat, which is hinged to a support column. A motor is fixedly connected to the connecting seat, and a cutter is rotatably connected to the connecting seat. The motor and the cutter are connected by a sprocket and chain drive. The connecting seat is hinged to the support column, and the cylinder output shaft is hinged to the connecting seat.

[0011] Using the above technical solution, the cylinder output shaft extends and drives the connecting seat to rotate relative to the support column. The connecting seat drives the motor and the cutter to revolve relative to the moving plate. The motor drives the cutter to rotate relative to the connecting seat through the sprocket and chain.

[0012] Preferably, one of the rollers on the mounting plate has connecting blocks rotatably connected to both ends of one of the rollers, the connecting blocks being slidably connected to the mounting plate, and also includes a screw rod, which is horizontally rotatably connected to the mounting plate, threadedly connected to the connecting block at one end of the roller, and a rotating handle fixedly connected to the other end of the screw rod.

[0013] Using the above technical solution, rotating screw one moves the connecting block and drives the roller connected to it to move closer to and further away from another roller on the mounting plate, adjusting the distance between the two rollers. Placing paper tubes of different diameters between the two rollers can better support them.

[0014] Preferably, the adjusting mechanism is a second screw, which is horizontally threaded onto the lead screw slider. The axes of the second screw and the lead screw are perpendicular to each other. One end of the second screw is rotatably connected to the moving plate, and the other end of the second screw is fixedly connected to a handle.

[0015] Using the above technical solution, rotating screw two drives the moving plate to move, and the moving plate drives the mounting plate, rotating roller and cutting machine to move, so that the position between the cutting machine blade and the rotating roller is aligned with the paper tube. Preferably, the workbench is provided with an organ cover, the lead screw is located in the organ cover, and the lead screw slider is fixedly connected to the organ cover.

[0016] By adopting the above technical solution, the bellows cover blocks external dust, product debris and other impurities, preventing impurities from sticking to the lead screw and causing damage to it.

[0017] In summary, this utility model allows for simultaneous cutting and winding of the paper tube by moving the cutting machine synchronously with the paper tube being produced, thus improving work efficiency, providing good protection, and being easy to adjust. Attached Figure Description

The support rod 5 is slidably connected to the spindle 3, and a connecting column connects the support rod 5 and the connecting rod 4.

[0022] See Figure 1 , Figure 3 and Figure 5 A horizontal lead screw 11 is rotatably connected to the upper part of the worktable 1. An accordion cover 18 is installed on the worktable 1. The lead screw 11 is located in the accordion cover 18. The slider of the lead screw 11 is fixedly connected to the accordion cover 18. The slider of the lead screw 11 is slidably connected to a moving plate 6. A horizontal screw rod 17 is threadedly connected to the slider of the lead screw 11. A rotating handle 19 is fixedly connected to the end of the screw rod 17. The axes of the screw rod 17 and the lead screw 11 are perpendicular to each other. The end of the screw rod 17 is rotatably connected to the moving plate 6. The connecting rod 4 is fixedly connected to the moving plate 6.

[0023] See Figure 2 and Figure 6 A support column 8 is fixedly connected to the movable plate 6. A cutting machine is hinged to the support column 8. The cutting machine includes a connecting seat 12, which is hinged to the support column 8. A motor 13 is fixedly connected to the connecting seat 12, and a cutter 14 is rotatably connected to the connecting seat 12. The motor 13 and the cutter 14 are connected by a sprocket and a chain drive. The connecting seat 12 is hinged to the support column 8. A cylinder 10 is hinged to the movable plate 6, and the output shaft of the cylinder 10 is hinged to the connecting seat 12.

[0024] See Figure 4 and Figure 6A mounting plate 7 is connected to the movable plate 6. The mounting plate 7 is located below the cutting machine and also includes a screw 16 and two rotating rollers 9. One rotating roller 9 is rotatably connected to the upper part of the mounting plate 7, and the two ends of the other rotating roller 9 are respectively rotatably connected to connecting blocks 15. The connecting blocks 15 are slidably connected to the mounting plate 7. The screw 16 is rotatably connected to the mounting plate 7. The ends of the screw 16 are respectively fixedly connected to rotating handles 19, and the screw 16 is threadedly connected to the connecting block 15 at one end of the rotating roller 9. By rotating the screw 16, the slider connected to it moves, and drives the rotating roller 9 connected to it to move closer to and away from the other rotating roller 9 on the mounting plate 7. Adjusting the distance between the two rotating rollers 9 allows paper tubes of different diameters to be placed between the two rotating rollers 9 for better support. The cutter 14 of the cutting machine is located near the end of the rotating roller 9, and the spindle 3 is located above the rotating roller 9.

[0025] Working principle: The paper strip is spirally wound onto the mandrel 3 to form a paper tube. The paper strip continues to wind, and the wound paper tube moves forward spirally on the mandrel 3. The paper tube moves to the space between the two rotating rollers 9 on the mounting plate 7, where the rotating rollers 9 support the paper strip. The paper strip continues to wind into a paper tube. After the wound paper tube moves a certain distance to the outside of one end of the rotating rollers 9, the lead screw 11 rotates, and its slider drives the moving plate 6 to move. The moving plate 6 drives the cutter and connecting rod 4 to move, and the connecting rod 4 drives the support rod 5 to move. The cutting machine and the support rod 5 move at the same speed as the paper tube.

[0026] Simultaneously, the output shaft of cylinder 10 extends, pushing the cutter to rotate relative to the support column 8, causing the cutter to contact the paper tube. The cutter cuts the rotating paper tube. During cutting, the support rod 5 supports the inside of the paper tube, preventing deformation caused by the force exerted by the gas cutter on the hollow paper tube. The section of paper tube that has moved to the outer side of the end of the rotating roller 9 is cut off. The output shaft of cylinder 10 retracts, causing the cutter to separate from the paper tube. The moving mechanism then moves the cutter, rotating roller 9, and support rod 5 back. The support rod 5 leaves the cut paper tube, and the cut paper tube falls off the rotating roller 9. As the cutter returns, the paper strip continues to wind into a spiral and move forward. The cutter returns to its original position. When the paper tube moves a distance beyond the end of the support roller, the moving mechanism again drives the cutter to move along with the paper tube, cutting the paper tube.

[0027] This allows the cutter and paper tube to move synchronously, eliminating the need to stop winding the paper tube and enabling simultaneous cutting and winding, thus improving work efficiency.
